Amylose is linear polymer that contributes to the construction of starch . It is
straight form of starch which contains glucose units connected with (α-1,4-glycosidic) bonds.
Helical structure of amylose may contain hydrophobic contact area, creating cavitysuitable for
creation of inclusion complex. Surfactants play an important role in many practical
applications and are part of many products . They are used in chemical, pharmaceutical,
cosmetic, food, oil industry etc. Surfactants or surface active agents are organic compounds
comprising the hydrophilic groups and hydrophobic long chain hydrocarbon groups. The
formation of the inclusion complex was followed by potentiometric titration of amylose (0 ;
0.1 ; 0.5 ; 1 ; 2 and 4%) with hexadecyl – trimethyl ammonium bromide ( 4 x 10-3 mol dm- 3)
resulting in a shift of the critical micelle concentration. The formation of the inclusion
complex with amylose HTAB occurs so that hydrocarbon chain cationic surfactant HTAB can
be incorporated into a helix of amylose. Electrodes used during the experiment are
silver/silver chloride (Metrohm) as a reference electrode and surfactant – sensitive electrodes
with homemade plasticized PVC membrane.
